Description

Technical Field

[0001] The utility model relates to the technical field of identification plates, in particular to a positioning device for processing identification plates. Background Art

[0002] A signboard is a sign that indicates the direction, also called a billboard. Signs, such as toilet signs and road signs, can be called signboards. The definition is relatively broad. When processing signboards, they need to be fixed with a positioning device to prevent movement during the processing.

[0003] According to a search, Chinese patent document publication number CN217699707U discloses a road sign processing fixture. The sign is inserted into a placement hole, and a limit assembly temporarily secures the sign in the placement hole. A positioning assembly then secures a spray plate to a fixed plate for spraying. Alternatively, a paper with a pattern engraved on it is placed on the sign, and the spray plate secures the paper to the sign for spraying. The device is simple to operate and highly efficient, improving the efficiency of temporary sign production. However, while the fixture can position the sign, it is only suitable for signs of a single size, has poor versatility, and cannot be adjusted to suit the size of the sign. Utility Model Content
